What is an AML check for USDT TRC20?+
An AML (Anti-Money Laundering) check for USDT TRC20 is a blockchain forensics analysis that evaluates a TRON wallet address's transaction history and fund origins for connections to sanctioned entities, cryptocurrency mixers, darknet markets, ransomware operations, or known fraud. The result is a 0–100 risk score that helps you decide whether it is safe to transact with that address.
Is CheckAMLUSDT free to use?+
Yes. CheckAMLUSDT is completely free to use with no registration, no account, and no KYC requirement. You can check any USDT TRC20 or TRON address at any time without any cost or limit.
How does the AML risk score work?+
The risk score is calculated on a scale of 0 to 100. Scores 0–25 indicate low risk (clean address), 26–50 suggest moderate risk (minor indirect exposure), 51–75 indicate high risk (direct mixer or darknet links), and 76–100 are critical (sanctions hits or severe illicit exposure). The score is weighted based on the directness, volume, and recency of any identified risk connections.
What data sources do you use for AML screening?+
CheckAMLUSDT references over 50 databases including the OFAC SDN list, EU and UN sanctions lists, known mixer contract addresses (Tornado Cash and TRON equivalents), darknet market cluster data, ransomware payment databases maintained by blockchain forensics researchers, exchange risk databases, and community-reported scam/fraud address registries.
How many transaction hops does the scan trace?+
Our engine traces up to 10 hops of transaction history from the queried address. This means if funds passed through multiple wallets before reaching a sanctioned entity, the scan still detects the connection. Deeper hops are weighted with lower risk contribution so direct exposure always scores higher than distant indirect connections.
Can I check a TRON transaction hash instead of a wallet?+
Yes. You can enter either a TRON wallet address (starting with T) or a TRON transaction hash. When a transaction hash is entered, CheckAMLUSDT screens both the sender and receiver addresses and evaluates the specific transaction for risk indicators such as interaction with flagged smart contracts or known risk clusters.
Why should I check a USDT TRC20 address before transacting?+
Receiving USDT from a sanctioned or high-risk address can contaminate your own wallet with what is called "tainted funds." Some centralized exchanges freeze accounts that receive tainted USDT, even unknowingly. Checking a sender's address before accepting a transfer protects you from compliance risk, account freezes, and potential legal complications.
What does "mixer exposure" mean in the AML report?+
Mixer exposure means that some portion of the funds in a wallet have passed through a cryptocurrency mixing or tumbling service, which is used to obscure transaction history. Regulators and exchanges treat mixer exposure as a significant red flag because mixers are frequently used to launder stolen or illicit funds. Even receiving mixed funds unknowingly can trigger exchange compliance alerts.
Does CheckAMLUSDT store my queried address?+
Queried addresses are processed for the purpose of delivering scan results and may be used in aggregate, anonymized form to improve our risk models. We do not store personally identifiable information, require no login, and never associate queries with individual users. For full details, see our Privacy Policy.
What is OFAC and why does it matter for USDT?+
OFAC (the Office of Foreign Assets Control) is the U.S. Treasury agency that administers economic sanctions. OFAC has directly sanctioned cryptocurrency addresses, including TRON and Ethereum wallets. Tether (USDT issuer) cooperates with OFAC by blacklisting sanctioned addresses at the smart contract level — meaning those addresses cannot transfer USDT. Receiving or sending to a sanctioned address can constitute a legal violation for U.S. persons.
How often is the sanctions database updated?+
The OFAC SDN list and other government sanctions databases are synchronized daily. High-frequency threat intelligence sources such as darknet cluster data and mixer contract addresses are updated in near-real-time, typically within hours of new intelligence becoming available. The last update timestamp is displayed in the scan results.
Can exchanges freeze my USDT based on AML checks?+
Yes. Major centralized exchanges (Binance, OKX, Bybit, HTX and others) run their own AML screening on incoming deposits. If your USDT originates from or has passed through a high-risk address, the exchange may freeze the deposit, request an explanation, or in severe cases, report the activity to regulators. Using CheckAMLUSDT before depositing helps you anticipate and avoid such situations.
Is a high AML score proof of criminal activity?+
No. A high AML risk score is a probabilistic indicator, not legal proof of wrongdoing. It means the address has transaction history that pattern-matches known risk categories. There may be legitimate explanations — for example, a wallet may have received funds from an exchange that also serves high-risk clients. CheckAMLUSDT results should inform due diligence decisions, not substitute for legal or compliance judgment.
What is a "pig butchering" scam and can you detect it?+
Pig butchering (also called "sha zhu pan") is a romance/investment fraud where victims are groomed over weeks and then convinced to invest USDT into fake DeFi platforms, with funds stolen at withdrawal. CheckAMLUSDT's fraud cluster database includes thousands of identified pig butchering wallet clusters, primarily on TRON, allowing you to check if an address you've been given is associated with this type of scam.
What is "tainted USDT" and how do I avoid it?+
Tainted USDT refers to tokens that have passed through wallets associated with illicit activity. Because blockchain transactions are traceable, "taint" follows the tokens through transfers. To avoid receiving tainted USDT, always run a CheckAMLUSDT scan on the sender's address before accepting a transfer, especially for peer-to-peer transactions from unknown counterparties.
Does CheckAMLUSDT work for non-TRON networks?+
Yes. While CheckAMLUSDT specializes in TRON TRC20 USDT screening, the tool also supports AML checks on Ethereum (ERC20 USDT), BNB Chain, Polygon and other major networks. Simply select the relevant network from the dropdown in the scanner widget before entering the address.
What is Tether's blacklist and is it related to AML?+
Tether maintains a smart-contract-level blacklist that permanently freezes USDT in flagged wallets at law enforcement or OFAC request. Once blacklisted, USDT in that wallet cannot be transferred. CheckAMLUSDT's scanner checks whether an address appears on Tether's blacklist as part of its sanctions screening, so you know immediately if an address has had its USDT frozen.
Can I use CheckAMLUSDT for business compliance?+
CheckAMLUSDT is suitable for individual due diligence and preliminary business compliance screening. For regulated financial institutions, exchanges, or VASPs (Virtual Asset Service Providers) that require certified, audit-ready AML reports with SLA guarantees, we recommend contacting us about our enterprise compliance API which provides PDF reports, audit trails, and integration with existing compliance workflows.
How accurate is the AML risk score?+
CheckAMLUSDT achieves 99.8% precision on known-labeled addresses in our validation dataset. False positive rates (clean addresses incorrectly flagged) are below 0.3%. However, no AML tool achieves perfection due to constantly evolving laundering techniques and the probabilistic nature of blockchain graph analysis. Results should always be used as one input among several in a comprehensive compliance decision.
What should I do if I've already received tainted USDT?+
If you have unknowingly received tainted USDT, do not transfer it further. Consult with a crypto compliance attorney. If you operate a business, notify your compliance officer and document the circumstances. For exchange-related freezes, cooperate with the exchange's compliance team and provide documentation of the legitimate origin of the transaction from your side. Acting in good faith and documenting your due diligence efforts is important.
